Hi all need some help with USB Loaders and WiiMC

Hello to all of you.
I´ve found this cool site which helps me to hack my wii I got yesterday. I followed this guide "Softmod/Hack almost ANY Wii v13 3/30/2013" without any problem/error. The only problem is I cant run any USB loader / WiiMC correctly - or I think I cant run it correctly. Whenever I start any loader (or WiiMC) it freezes(without any attached USB disk) or restarts to main menu (with attached USB flashdisk).Do I need to have any USB disk attached just to run it at least to some menu ? Is there anything I need to check ?

Sorry If its already discussed here I didnt have a luck to search it here.

sorry guys I havent introduced myself. I am 33 years old guy preparing my wii for my nephew ... and looking forward I can play Zelda finally :-)
I ´ve just realized I copied apps incorrectly on SD card ... yesterday it was quite late while I read the guide several times :-)
Anyway thanks for quick response
